Summary of Related Art

Improvements in the specificity of agents used to treat cancer is of considerable interest because of the therapeutic benefits which would be realized if the side effects associated with the administration of these agents could be reduced. Traditionally, dramatic improvements in the treatment of cancer are associated with identification of therapeutic agents acting through novel mechanisms.

Protein kinases are enzymes that catalyze the phosphorylation of proteins, in particular, hydroxy groups on tyrosine, serine and threonine residues of proteins. The consequences of this seemingly simple activity are staggering; cell differentiation and proliferation; i.e., virtually all aspects of cell life in one-way or another depend on protein kinase activity. Furthermore, abnormal protein kinase activity has been related to a host of disorders, ranging from relatively non-life threatening diseases such as psoriasis to extremely virulent diseases such as glioblastoma (brain cancer).

Protein kinases can be categorized as receptor type or non-receptor type. Receptor-type tyrosine kinases have an extracellular, a transmembrane, and an intracellular domain, while non-receptor type tyrosine kinases are wholly intracellular.

Receptor-type tyrosine kinases are comprised of a large number of transmembrane receptors with diverse biological activity. In fact, about twenty different subfamilies of receptor-type tyrosine kinases have been identified. One tyrosine kinase subfamily, designated the HER subfamily, is comprised of EGFR (HER1), HER2, HER3, and HER4. Ligands of this subfamily of receptors identified so far include epithelial growth factor, TGF-alpha, amphiregulin, HB-EGF, betacellulin and heregulin. Another subfamily of these receptor-type tyrosine kinases is the insulin subfamily, which includes INS-R, IGF-IR, and IR-R. The PDGF subfamily includes the PDGF-alpha and beta-receptors, CSFIR, c-kit and FLK-II. Additionally there is the FLK family, which is comprised of the kinase insert domain receptor (KDR), fetal liver kinase-1 (FLK-1), fetal liver kinase-4 (FLK-4) and the fms-like tyrosine kinase-1 (flt-1). The PDGF and FLK families are usually considered together due to the similarities of the two groups. For a detailed discussion of the receptor-type tyrosine kinases, see Plowman et al., DN&P 7(6): 334-339, 1994, which is hereby incorporated by reference for all purposes.

The non-receptor type of tyrosine kinases is also comprised of numerous subfamilies, including Src, Frk, Btk, Csk, Abl, Zap70, Fes/Fps, Fak, Jak, Ack, and LIMK. Each of these subfamilies is further sub-divided into varying receptors. For example, the Src subfamily is one of the largest and includes Src, Yes, Fyn, Lyn, Lck, Blk, Hck, Fgr, and Yrk. The Src subfamily of enzymes has been linked to oncogenesis. For a more detailed discussion of the non-receptor type of tyrosine kinases, see Bolen, Oncogene, 8:2025-2031 (1993), which is hereby incorporated by reference for all purposes.

Since protein kinases and their ligands play critical roles in various cellular activities, deregulation of protein kinase enzymatic activity can lead to altered cellular properties, such as uncontrolled cell growth associated with cancer. In addition to oncological indications, altered kinase signaling is implicated in numerous other pathological diseases. These include, but are not limited to: immunological disorders, cardiovascular diseases, inflammatory diseases, and degenerative diseases. Therefore, both receptor and non-receptor protein kinases are attractive targets for small molecule drug discovery.

One particularly attractive goal for therapeutic use of kinase modulation relates to oncological indications. For example, modulation of protein kinase activity for the treatment of cancer has been demonstrated successfully with the FDA approval of Gleevec® (imatinib mesylate, produced by Novartis Pharmaceutical Corporation of East Hanover, N.J.) for the treatment of Chronic Myeloid Leukemia (CML) and gastrointestinal stroma cancers (GIST). Gleevec is a c-Kit and Abl kinase inhibitor.

Modulation (particularly inhibition) of cell proliferation and angiogenesis, two key cellular processes needed for tumor growth and survival (Matter A. Drug Disc Technol 2001 6, 1005-1024), is an attractive goal for development of small-molecule drugs. Anti-angiogenic therapy represents a potentially important approach for the treatment of solid tumors and other diseases associated with dysregulated vascularization, including ischemic coronary artery disease, diabetic retinopathy, psoriasis and rheumatoid arthritis. As well, cell antiproliferative agents are desirable to slow or stop the growth of tumors.

Inhibition of EGF, VEGF and ephrin signal transduction will prevent cell proliferation and angiogenesis, two key cellular processes needed for tumor growth and survival (Matter A. Drug Disc Technol 2001 6, 1005-1024). VEGF receptors are previously described targets for small molecule inhibition.

The Eph receptors comprise the largest family of receptor tyrosine kinases and are divided into two groups, EphA and EphB, based on their sequence homology. The ligands for the Eph receptors are ephrin, which are membrane anchored. Ephrin A ligands bind preferentially to EphA receptors whilst ephrin B ligands bind to EphB receptors. Binding of ephrin to Eph receptors causes receptor autophosphorylation and typically requires a cell-cell interaction since both receptor and ligand are membrane bound.

Overexpression of Eph receptors has been linked to increased cell proliferation in a variety of tumors (Zhou R 1998 Pharmacol Ther. 77, 151-181; Kiyokawa E, Takai S, Tanaka M et al 1994 Cancer Res 54, 3645-3650; Takai N Miyazaki T, Fujisawa K, Nasu K and Miyakawa. 2001 Oncology reports 8, 567-573). The family of Eph receptor tyrosine kinases and their ephrin ligands play important roles in a variety of processes during embryonic development and also in pathological angiogenesis and potentially metastasis. Therefore modulation of Eph receptor kinase activity should provide means to treat or prevent disease states associated with abnormal cell proliferation such as those described above.

The epidermal growth factor receptor (EGFR, HER1, erbB1) is part of a family of plasmam membrane receptor tyrosine kinases that control cellular growth, proliferation and apoptosis. The ligand for EGFR is the epidermal growth factor and dysregulation of the EGFR signal transduction pathway has been implicated in tumorigenesis and cancer progression thus making it a clinically relevant target for novel anticancer treatments Drevs J et al 2003 Curr Drug Targets 4, 113-121; Ciardiello F and Tortora G. 2001 Clin. Cancer Res. 7, 2958-2970; Thomas M. 2002 Semin Onc. Nurs. 18, 20-27).

EGFR is overexpressed in different human cancers especially non-small cell lung cancer and glioblastomas. In these cancers, EGFR overexpression is commonly associated with advanced disease and poor prognosis (Baselga J et al 1999 Semin. Oncol. 26, 78-83).

Accordingly, the identification of small-molecule compounds that specifically inhibit, regulate and/or modulate the signal transduction of tyrosine kinases, particularly ephrin and EGFR receptor kinases, is desirable as a means to treat or prevent disease states associated with abnormal cell proliferation and is an object of this invention.

SUMMARY OF THE INVENTION

In one aspect, the present invention provides compounds for modulating kinase activity, particularly ephrin receptor kinase (from herein denoted “ephrin”) activity and/or EGFR activity; methods of treating diseases mediated by such activity utilizing the compounds and pharmaceutical compositions thereof. Diseases mediated by ephrin include, but are not limited to, diseases characterized in part by abnormal cell migration and invasion and angiogenesis associated with tumor growth. Diseases mediated by EGF driven signal transduction include, but are not limited to, diseases characterized by abnormal levels of cell proliferation (i.e. tumor growth) and programmed cell death (apoptosis). Diseases mediated by both ephrin and EGF include diseases characterized by both abnormal cell proliferation and angiogenesis which are associated with tumor growth.

Inhibitors that are selective for a particular kinase, for example ephrin and EGFR, are included in this invention. However, another aspect of the invention are compounds that inhibit, regulate and/or modulate the signal transduction receptor tyrosine kinase families, family members, or otherwise related sets of kinases. Such related kinase families may include receptor-type tyrosine kinases of the HER, FLK and insulin subfamilies, which demonstrate similarity in both structure and broad biochemical function. Thus quinazolines of the invention include “spectrum selective” kinase modulators. “Spectrum selective” kinase modulators are defined as quinazolines of the invention that inhibit, regulate and/or modulate signal transduction across various subfamilies of receptor-type tyrosine kinases including those of ephrin and EGFR receptor tyrosine kinase subfamilies.

In another aspect, the invention provides methods of screening for modulators of receptor tyrosine kinase activity, for example activity of ephrin and EGFR. The methods comprise combining a composition of the invention, a receptor tyrosine kinase, and at least one candidate agent and determining the effect of the candidate agent on the kinase activity.

In yet another aspect, the invention also provides pharmaceutical kits comprising one or more containers filled with one or more of the ingredients of pharmaceutical compounds and/or compositions of the present invention, including, one or more tyrosine receptor kinase activity modulators as described herein. Such kits can also include, for example, other compounds and/or compositions (for example, diluents, permeation enhancers, lubricants, and the like), a device(s) for administering the compounds and/or compositions, and written instructions in a form prescribed by a governmental agency regulating the manufacture, use or sale of pharmaceuticals or biological products, which instructions can also reflects approval by the agency of manufacture, use or sale for human administration.

In still yet another aspect, the invention also provides a diagnostic agent comprising a compound of the invention and, optionally, pharmaceutically acceptable adjuvants and excipients.

These and other features and advantages of the present invention will be described in more detail below with reference to the associated drawings.

DETAILED DESCRIPTION OF THE INVENTION

The compositions of the invention are used to treat diseases associated with abnormal and or unregulated cellular activities.

Definitions

As used in the present specification, the following words and phrases are generally intended to have the meanings as set forth below, except to the extent that the context in which they are used indicates otherwise or they are expressly defined to mean something different.

The atom numbering convention for the quinazoline structure is as follows:

The symbol “—” means a single bond, “=” means a double bond, “≡” means a triple bond. The symbol “

” refers to a group on a double-bond as occupying either position on the terminus of a double bond to which the symbol is attached; that is, the geometry, E- or Z-, of the double bond is ambiguous. When a group is depicted removed from its parent formula, the “

” symbol will be used at the end of the bond which was theoretically cleaved in order to separate the group from its parent structural formula.

If a group “R” is depicted as “floating” on a ring system, as for example in the formula:

then, unless otherwise defined, a substituent “R” may reside on any atom of the ring system, assuming replacement of a depicted, implied, or expressly defined hydrogen from one of the ring atoms, so long as a stable structure is formed.

If a group “R” is depicted as floating on a fused ring system, as for example in the formulae:

then, unless otherwise defined, a substituent “R” may reside on any atom of the fused ring system, assuming replacement of a depicted (for example the —NH— in the formula above), implied (for example as in the formula above, where the hydrogens are not shown but understood to be present), or expressly defined hydrogen (for example where in the formula above, “X” equals —CH—) from one of the ring atoms, so long as a stable structure is formed. In the example depicted, the “R” group may reside on either the 5-membered or the 6-membered ring of the fused ring system. In the formula depicted above, when y is 2 for example, then the two “R's” may reside on any two atoms of the ring system, again assuming each replaces a depicted, implied, or expressly defined hydrogen on the ring.

When there are more than one such depicted “floating” groups, as for example in the formulae:

where there are two groups, namely, the “R” and the bond indicating attachment to a parent structure; then, unless otherwise defined, the “floating” groups may reside on any atoms of the ring system, again assuming each replaces a depicted, implied, or expressly defined hydrogen on the ring.

When a group “R” is depicted as existing on a ring system containing saturated carbons, as for example in the formula:

where, in this example, “y” can be more than one, assuming each replaces a currently depicted, implied, or expressly defined hydrogen on the ring; then, unless otherwise defined, where the resulting structure is stable, two “R's” may reside on the same carbon. A simple example is when R is a methyl group; there can exist a geminal dimethyl on a carbon of the depicted ring (an “annular” carbon). In another example, two R's on the same carbon, including that carbon, may form a ring, thus creating a spirocyclic ring (a “spirocyclyl” group) structure with the depicted ring as for example in the formula:

“Alkyl” is intended to include linear, branched, or cyclic hydrocarbon structures and combinations thereof, inclusively. For example, “C₈ alkyl” may refer to an n-octyl, iso-octyl, cyclohexylethyl, and the like. Lower alkyl refers to alkyl groups of from one to six carbon atoms. Examples of lower alkyl groups include methyl, ethyl, propyl, isopropyl, butyl, s-butyl, t-butyl, isobutyl, pentyl, hexyl and the like. Higher alkyl refers to alkyl groups containing more that eight carbon atoms. Exemplary alkyl groups are those of C₂₀ or below. Cycloalkyl is a subset of alkyl and includes cyclic hydrocarbon groups of from three to thirteen carbon atoms. Examples of cycloalkyl groups include c-propyl, c-butyl, c-pentyl, norbornyl, adamantyl and the like. In this application, alkyl refers to alkanyl, alkenyl, and alkynyl residues (and combinations thereof); it is intended to include cyclohexylmethyl, vinyl, allyl, isoprenyl, and the like. Thus when an alkyl residue having a specific number of carbons is named, all geometric isomers having that number of carbons are intended to be encompassed; thus, for example, either “butyl” or “C₄ alkyl” is meant to include n-butyl, sec-butyl, isobutyl, t-butyl, isobutenyl and but-2-yne radicals; and “propyl” or “C₃ alkyl” each include n-propyl, propenyl, and isopropyl.

“Alkylene” refers to straight or branched chain divalent radical consisting solely of carbon and hydrogen atoms, containing no unsaturation and having from one to ten carbon atoms, for example, methylene, ethylene, propylene, n-butylene and the like. Alkylene is a subset of alkyl, referring to the same residues as alkyl, but having two points of attachment and, specifically, fully saturated. Examples of alkylene include ethylene (—CH₂CH₂—), propylene (—CH₂CH₂CH₂—), dimethylpropylene (—CH₂C(CH₃)₂CH₂—), and cyclohexylpropylene (—CH₂CH₂CH(C₆H₁₃)).

“Alkylidene” refers to a straight or branched chain unsaturated divalent radical consisting solely of carbon and hydrogen atoms, having from two to ten carbon atoms, for example, ethylidene, propylidene, n-butylidene, and the like. Alkylidene is a subset of alkyl, referring to the same residues as alkyl, but having two points of attachment and, specifically, double bond unsaturation. The unsaturation present includes at least one double bond and a double bond can exist between the first carbon of the chain and a carbon atom of the rest of the molecule to which it is attached.

Any of the above radicals, “alkylene,” “alkylidene” and “alkylidyne,” when optionally substituted, may contain alkyl substitution which itself contains unsaturation. For example, 2-(2-phenylethynyl-but-3-enyl)-naphthalene (IUPAC name) contains an n-butylid-3-ynyl radical with a vinyl substituent at the 2-position of said radical.

Typically, but not necessarily, fused-polycyclics share a vicinal set of atoms. Typically, a Spiro ring system is not a fused-polycyclic by this definition, but fused polycyclic ring systems of the invention may themselves have spiro rings attached thereto via a single ring atom of the fused-polycyclic.

“Halogen” or “halo” refers to fluorine, chlorine, bromine or iodine. Dihaloaryl, dihaloalkyl, trihaloaryl etc. refer to aryl and alkyl substituted with a plurality of halogens, but not necessarily a plurality of the same halogen; thus 4-chloro-3-fluorophenyl is within the scope of dihaloaryl.

“Heteroatom” refers to O, S, N, or P.

“Heterocyclyl” refers to a stable three- to fifteen-membered ring radical that consists of carbon atoms and from one to five heteroatoms selected from the group consisting of nitrogen, phosphorus, oxygen and sulfur. For purposes of this invention, the heterocyclyl radical may be a monocyclic, bicyclic or tricyclic ring system, which may include fused or bridged ring systems, and the nitrogen, phosphorus, carbon or sulfur atoms in the heterocyclyl radical may be optionally oxidized to various oxidation states.

The heterocyclyl, alkylene, alkylidene, or alkylidyne radical portion of an arylalkyl group may be optionally substituted. “Lower heterocyclylalkyl” refers to an arylalkyl where the “alkyl” portion of the group has one to six carbons.

“Hydrocarbyl” refers to a hydrocarbon residue, generally. The term “hydrocarbyl” can be modified to mean more specific structures, for example “a saturated or mono- or poly-unsaturated C₃-C₁₄ mono- or fused-polycyclic hydrocarbyl optionally containing one, two, or three annular heteroatoms per ring” means a mono- or polycyclic (for example a bridged bicyclic) ring system, having between three and fourteen-ring atoms, that contains only carbon ring atoms, but optionally can contain up to three heteratoms per ring and/or unsaturation.

“Optional” or “optionally” means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances in which it does not. It will be understood by those skilled in the art with respect to any group containing one or more substituents that such groups are not intended to introduce any substitution or substitution patterns (for example, substituted alkyl includes optionally substituted cycloalkyl groups, which in turn are defined as including optionally substituted alkyl groups) that are sterically impractical and/or synthetically non-feasible. “Optionally substituted” refers to all subsequent modifiers in a term, for example in the term “optionally substituted arylC₁₋₈ alkyl,” optional substitution may occur on both the “C₁₋₈ alkyl” portion and the “aryl” portion of the molecule; and for example, optionally substituted alkyl includes optionally substituted cycloalkyl groups, which in turn are defined as including optionally substituted alkyl groups.

Such a system may contain isolated or conjugated unsaturation, but not aromatic or heteroaromatic rings in its core structure (but may have aromatic substitution thereon). For example, 2,3,3a,4,7,7a-hexahydro-1H-indene, 7-aza-bicyclo[2.2.1]heptane and 1,2,3,4,4a,5,8,8a-octahydro-naphthalene are all included in the class “saturated bridged ring system.”

“Spirocyclyl” or “spirocyclic ring” refers to a ring originating from a particular annular carbon of another ring. For example, a ring atom of the aforementioned saturated bridged ring system, but not a bridgehead atom, can be a shared atom between the saturated bridged ring system (rings B and B′) and a spirocyclyl (ring A) attached thereto, as depicted below. A spirocyclyl can be either carbocyclic or heterocyclic

“Yield” for each of the reactions described herein is expressed as a percentage of the theoretical yield.

In some embodiments, as will be appreciated by those skilled in the art, two adjacent groups on an aromatic system may be fused together to form a ring structure. The fused ring structure may contain heteroatoms and may be optionally substituted with one or more groups. It should additionally be noted that saturated carbons of such fused groups (i.e. saturated ring structures) can contain two substitution groups.

Some of the compounds of the invention may have imino, amino, oxo or hydroxy substituents off aromatic heterocyclyl systems. For purposes of this disclosure, it is understood that such imino, amino, oxo or hydroxy substituents may exist in their corresponding tautomeric form, i.e., amino, imino, hydroxy or oxo, respectively.

Compounds of the invention are generally named using ACD/Name (available from Advanced Chemistry Development, Inc. of Toronto, Canada). This software derives names from chemical structures according to systematic application of the nomenclature rules agreed upon by the International Union of Pure and Applied Chemistry (IUPAC), International Union of Biochemistry and Molecular Biology (IUBMB), and the Chemical Abstracts Service (CAS).

The compounds of the invention, or their pharmaceutically acceptable salts, may have asymmetric carbon atoms, oxidized sulfur atoms or quaternized nitrogen atoms in their structure.

The compounds of the invention and their pharmaceutically acceptable salts may exist as single stereoisomers, racemates, and as mixtures of enantiomers and diastereomers. The compounds may also exist as geometric isomers. All such single stereoisomers, racemates and mixtures thereof, and geometric isomers are intended to be within the scope of this invention.

It is assumed that when considering generic descriptions of compounds of the invention for the purpose of constructing a compound, such construction results in the creation of a stable structure. That is, one skilled in the art would recognize that there can theoretically be some constructs which would not normally be considered as stable compounds. Stable constructs for the saturated bridged ring system as represented by X¹, X², and optionally X³ of formula II include but are not limited to motifs such as: 1) where heteroatoms of a ring or bridge thereon are bonded directly to each other, for example a bridge containing a sulfonamide, 2) where heteroatoms of a ring or bridge thereon are separated by only one carbon, for example a urea, carbamate, acetal, aminal, thioacetal, thioaminal, amidine, guanidine, and the like, 3) where heteroatoms of a ring or bridge thereon are separated by two or more carbons, for example an —NHCH₂CH₂O— bridge, and the like, and 4) where heteroatoms in the bridged ring system are separated by more than two carbon atoms, for example wherein the bridged ring system is a decahydro-isoquinoline.

When a particular group with its bonding structure is denoted as being bonded to two partners, for example a linking group such as —OCH₂—, then it is understood that either of the two partners may be bound to the particular group at one end, and the other partner is necessarily bound to the other end of the particular group, unless stated explicitly otherwise.

Methods for the preparation and/or separation and isolation of single stereoisomers from racemic mixtures or non-racemic mixtures of stereoisomers are well known in the art. For example, optically active (R)- and (S)-isomers may be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. When desired, the R- and S-isomers may be resolved by methods known to those skilled in the art, for example by: formation of diastereoisomeric salts or complexes which may be separated, for example, by crystallization; via formation of diastereoisomeric derivatives which may be separated, for example, by crystallization, gas-liquid or liquid chromatography; selective reaction of one enantiomer with an enantiomer-specific reagent, for example enzymatic oxidation or reduction, followed by separation of the modified and unmodified enantiomers; or gas-liquid or liquid chromatography in a chiral environment, for example on a chiral support, such as silica with a bound chiral ligand or in the presence of a chiral solvent. It will be appreciated that where a desired enantiomer is converted into another chemical entity by one of the separation procedures described above, a further step may be required to liberate the desired enantiomeric form. Alternatively, specific enantiomer may be synthesized by asymmetric synthesis using optically active reagents, substrates, catalysts or solvents, or by converting on enantiomer to the other by asymmetric transformation. For a mixture of enantiomers, enriched in a particular enantiomer, the major component enantiomer may be further enriched (with concomitant loss in yield) by recrystallization.

“Patient” for the purposes of the present invention includes humans and other animals, particularly mammals, and other organisms. Thus the methods are applicable to both human therapy and veterinary applications. In a preferred embodiment the patient is a mammal, and in a most preferred embodiment the patient is human.

“Kinase-dependent diseases or conditions” refer to pathologic conditions that depend on the activity of one or more protein kinases. Kinases either directly or indirectly participate in the signal transduction pathways of a variety of cellular activities including proliferation, adhesion, migration, differentiation and invasion. Diseases associated with kinase activities include tumor growth, the pathologic neovascularization that supports solid tumor growth, and associated with other diseases where excessive local vascularization is involved such as ocular diseases (diabetic retinopathy, age-related macular degeneration, and the like) and inflammation (psoriasis, rheumatoid arthritis, and the like).

While not wishing to be bound to theory, phosphatases can also play a role in “kinase-dependent diseases or conditions” as cognates of kinases; that is, kinases phosphorylate and phosphatases dephosphorylate, for example protein substrates. Therefore compounds of the invention, while modulating kinase activity as described herein, may also modulate, either directly or indirectly, phosphatase activity. This additional modulation, if present, may be synergistic (or not) to activity of compounds of the invention toward a related or otherwise interdependent kinase or kinase family. In any case, as stated previously, the compounds of the invention are useful for treating diseases characterized in part by abnormal levels of cell proliferation (i.e. tumor growth), programmed cell death (apoptosis), cell migration and invasion and angiogenesis associated with tumor growth.

“Therapeutically effective amount” is an amount of a compound of the invention, that when administered to a patient, ameliorates a symptom of the disease. The amount of a compound of the invention which constitutes a “therapeutically effective amount” will vary depending on the compound, the disease state and its severity, the age of the patient to be treated, and the like. The therapeutically effective amount can be determined routinely by one of ordinary skill in the art having regard to his own knowledge and to this disclosure.

Pharm. Sci., 1977:66:1-19 which is incorporated herein by reference.)

“Prodrug” refers to compounds that are transformed (typically rapidly) in vivo to yield the parent compound of the above formulae, for example, by hydrolysis in blood. Common examples include, but are not limited to, ester and amide forms of a compound having an active form bearing a carboxylic acid moiety.

Roche, American Pharmaceutical Association and Pergamon Press, 1987, both of which are incorporated herein by reference for all purposes.

“Metabolite” refers to the break-down or end product of a compound or its salt produced by metabolism or biotransformation in the animal or human body; for example, biotransformation to a more polar molecule such as by oxidation, reduction, or hydrolysis, or to a conjugate (see Goodman and Gilman, “The Pharmacological Basis of Therapeutics” 8.sup.th Ed., Pergamon Press, Gilman et al. (eds), 1990 for a discussion of biotransformation). As used herein, the metabolite of a compound of the invention or its salt may be the biologically active form of the compound in the body. In one example, a prodrug may be used such that the biologically active form, a metabolite, is released in vivo. In another example, a biologically active metabolite is discovered serendipitously, that is, no prodrug design per se was undertaken. An assay for activity of a metabolite of a compound of the present invention is known to one of skill in the art in light of the present disclosure.

In addition, the compounds of the present invention can exist in unsolvated as well as solvated forms with pharmaceutically acceptable solvents such as water, ethanol, and the like. In general, the solvated forms are considered equivalent to the unsolvated forms for the purposes of the present invention.

In the case of capsules, tablets, and pills, the dosage forms may also comprise buffering agents.

Solid dosage forms as described above can be prepared with coatings and shells, such as enteric coatings and others well known in the art. They may contain pacifying agents, and can also be of such composition that they release the active compound or compounds in a certain part of the intestinal tract in a delayed manner. Examples of embedded compositions that can be used are polymeric substances and waxes. The active compounds can also be in microencapsulated form, if appropriate, with one or more of the above-mentioned excipients.

Compositions for rectal administrations are, for example, suppositories that can be prepared by mixing the compounds of the present invention with for example suitable non-irritating excipients or carriers such as cocoa butter, polyethyleneglycol or a suppository wax, which are solid at ordinary temperatures but liquid at body temperature and therefore, melt while in a suitable body cavity and release the active component therein.

Dosage forms for topical administration of a compound of this invention include ointments, powders, sprays, and inhalants. The active component is admixed under sterile conditions with a physiologically acceptable carrier and any preservatives, buffers, or propellants as may be required. Ophthalmic formulations, eye ointments, powders, and solutions are also contemplated as being within the scope of this invention.

Generally, depending on the intended mode of administration, the pharmaceutically acceptable compositions will contain about 1% to about 99% by weight of a compound(s) of the invention, or a pharmaceutically acceptable salt thereof, and 99% to 1% by weight of a suitable pharmaceutical excipient. In one example, the composition will be between about 5% and about 75% by weight of a compound(s) of the invention, or a pharmaceutically acceptable salt thereof, with the rest being suitable pharmaceutical excipients.

Actual methods of preparing such dosage forms are known, or will be apparent, to those skilled in this art; for example, see Remington's Pharmaceutical Sciences, 18th Ed., (Mack Publishing Company, Easton, Pa., 1990). The composition to be administered will, in any event, contain a therapeutically effective amount of a compound of the invention, or a pharmaceutically acceptable salt thereof, for treatment of a disease-state in accordance with the teachings of this invention.

The compounds of the invention, or their pharmaceutically acceptable salts, are administered in a therapeutically effective amount which will vary depending upon a variety of factors including the activity of the specific compound employed, the metabolic stability and length of action of the compound, the age, body weight, general health, sex, diet, mode and time of administration, rate of excretion, drug combination, the severity of the particular disease-states, and the host undergoing therapy. The compounds of the present invention can be administered to a patient at dosage levels in the range of about 0.1 to about 1,000 mg per day. For a normal human adult having a body weight of about 70 kilograms, a dosage in the range of about 0.01 to about 100 mg per kilogram of body weight per day is an example. The specific dosage used, however, can vary. For example, the dosage can depend on a number of factors including the requirements of the patient, the severity of the condition being treated, and the pharmacological activity of the compound being used. The determination of optimum dosages for a particular patient is well known to those skilled in the art.

Utility of Compounds of the Invention as Screening Agents

To employ the compounds of the invention in a method of screening for candidate agents that bind to, for example ephrin or EGFR receptor kinase, the protein is bound to a support, and a compound of the invention is added to the assay. Alternatively, the compound of the invention is bound to the support and the protein is added. Classes of candidate agents among which novel binding agents may be sought include specific antibodies, non-natural binding agents identified in screens of chemical libraries, peptide analogs, etc. Of particular interest are screening assays for candidate agents that have a low toxicity for human cells. A wide variety of assays may be used for this purpose, including labeled in vitro protein-protein binding assays, electrophoretic mobility shift assays, immunoassays for protein binding, functional assays (phosphorylation assays, etc.) and the like.

The determination of the binding of the candidate agent to, for example ephrin or EGFR protein, may be done in a number of ways. In one example, the candidate agent (the compound of the invention) is labeled, for example, with a fluorescent or radioactive moiety and binding determined directly. For example, thus may be done by attaching all or a portion of ephrin or EGFR protein to a solid support, adding a labeled agent (for example a compound of the invention in which at least one atom has been replaced by a detectable isotope), washing off excess reagent, and determining whether the amount of the label is that present on the solid support. Various blocking and washing steps may be utilized as is known in the art.

By “labeled” herein is meant that the compound is either directly or indirectly labeled with a label which provides a detectable signal, for example, radioisotope, fluorescent tag, enzyme, antibodies, particles such as magnetic particles, chemiluminescent tag, or specific binding molecules, etc. Specific binding molecules include pairs, such as biotin and streptavidin, digoxin and antidigoxin etc. For the specific binding members, the complementary member would normally be labeled with a molecule which provides for detection, in accordance with known procedures, as outlined above. The label can directly or indirectly provide a detectable signal.

In some embodiments, only one of the components is labeled. For example, ephrin or EGFR protein may be labeled at tyrosine positions using ¹²⁵I, or with fluorophores. Alternatively, more than one component may be labeled with different labels; using ¹²⁵I for the proteins, for example, and a fluorophor for the candidate agents.

The compounds of the invention may also be used as competitors to screen for additional drug candidates. “Candidate bioactive agent” or “drug candidate” or grammatical equivalents as used herein describe any molecule, for example, protein, oligopeptide, small organic molecule, polysaccharide, polynucleotide, etc., to be tested for bioactivity. They may be capable of directly or indirectly altering the cellular proliferation phenotype or the expression of a cellular proliferation sequence, including both nucleic acid sequences and protein sequences. In other cases, alteration of cellular proliferation protein binding and/or activity is screened. In the case where protein binding or activity is screened, some embodiments exclude molecules already known to bind to that particular protein. Exemplary embodiments of assays described herein include candidate agents, which do not bind the target protein in its endogenous native state, termed herein as “exogenous” agents. In one example, exogenous agents further exclude antibodies to ephrin or EGFR.

Candidate agents can encompass numerous chemical classes, though typically they are organic molecules having a molecular weight of more than about 100 and less than about 2,500 daltons. Candidate agents comprise functional groups necessary for structural interaction with proteins, particularly hydrogen bonding and lipophilic binding, and typically include at least an amine, carbonyl, hydroxyl, ether, or carboxyl group, for example at least two of the functional chemical groups. The candidate agents often comprise cyclical carbon or heterocyclyl structures and/or aromatic or polyaromatic structures substituted with one or more of the above functional groups. Candidate agents are also found among biomolecules including peptides, saccharides, fatty acids, steroids, purines, pyrimidines, derivatives, structural analogs, or combinations thereof.

Candidate agents are obtained from a wide variety of sources including libraries of synthetic or natural compounds. For example, numerous means are available for random and directed synthesis of a wide variety of organic compounds and biomolecules, including expression of randomized oligonucleotides. Alternatively, libraries of natural compounds in the form of bacterial, fungal, plant and animal extracts are available or readily produced. Additionally, natural or synthetically produced libraries and compounds are readily modified through conventional chemical, physical and biochemical means. Known pharmacological agents may be subjected to directed or random chemical modifications, such as acylation, alkylation, esterification, amidification to produce structural analogs.

In one example, the binding of the candidate agent is determined through the use of competitive binding assays. In this example, the competitor is a binding moiety known to bind to ephrin or EGFR, such as an antibody, peptide, binding partner, ligand, etc. Under certain circumstances, there may be competitive binding as between the candidate agent and the binding moiety, with the binding moiety displacing the candidate agent.

In some embodiments, the candidate agent is labeled. Either the candidate agent, or the competitor, or both, is added first to ephrin or EGFR for a time sufficient to allow binding, if present. Incubations may be performed at any temperature that facilitates optimal activity, typically between 4° C. and 40° C.

Incubation periods are selected for optimum activity, but may also be optimized to facilitate rapid high throughput screening. Typically between 0.1 and 1 hour will be sufficient. Excess reagent is generally removed or washed away. The second component is then added, and the presence or absence of the labeled component is followed, to indicate binding.

In one example, the competitor is added first, followed by the candidate agent. Displacement of the competitor is an indication the candidate agent is binding to ephrin or EGFR and thus is capable of binding to, and potentially modulating, the activity of ephrin or EGFR. In this embodiment, either component can be labeled. Thus, for example, if the competitor is labeled, the presence of label in the wash solution indicates displacement by the agent. Alternatively, if the candidate agent is labeled, the presence of the label on the support indicates displacement.

In an alternative embodiment, the candidate agent is added first, with incubation and washing, followed by the competitor. The absence of binding by the competitor may indicate the candidate agent is bound to ephrin or EGFR with a higher affinity. Thus, if the candidate agent is labeled, the presence of the label on the support, coupled with a lack of competitor binding, may indicate the candidate agent is capable of binding to ephrin or EGFR.

It may be of value to identify the binding site of, for example, ephrin or EGFR. This can be done in a variety of ways. In one embodiment, once ephrin or EGFR has been identified as binding to the candidate agent, ephrin or EGFR is fragmented or modified and the assays repeated to identify the necessary components for binding.

Modulation is tested by screening for candidate agents capable of modulating the activity of ephrin or EGFR comprising the steps of combining a candidate agent with ephrin or EGFR, as above, and determining an alteration in the biological activity of ephrin or EGFR. Thus, in this embodiment, the candidate agent should both bind to (although this may not be necessary), and alter its biological or biochemical activity as defined herein. The methods include both in vitro screening methods and in vivo screening of cells for alterations in cell viability, morphology, and the like.

Alternatively, differential screening may be used to identify drug candidates that bind to native ephrin or EGFR, but cannot bind to modified ephrin or EGFR.

Positive controls and negative controls may be used in the assays. For example, all control and test samples are performed in at least triplicate to obtain statistically significant results. Incubation of samples is for a time sufficient for the binding of the agent to the protein. Following incubation, samples are washed free of non-specifically bound material and the amount of bound, generally labeled agent determined. For example, where a radiolabel is employed, the samples may be counted in a scintillation counter to determine the amount of bound compound.

A variety of other reagents may be included in the screening assays. These include reagents like salts, neutral proteins, for example, albumin, detergents, etc which may be used to facilitate optimal protein-protein binding and/or reduce non-specific or background interactions. Also reagents that otherwise improve the efficiency of the assay, such as protease inhibitors, nuclease inhibitors, anti-microbial agents, etc., may be used. The mixture of components may be added in any order that provides for the requisite binding.

Scheme 1 depicts a general synthetic route for compounds of the invention and is not intended to be limiting. Specific examples are described subsequently to this general synthetic description. A benzoic ester 1, where R is typically but not necessarily a methyl radical and P is typically but not necessarily an alkyl group, is O-alkylated at the oxygen para to the carboxylate group with an electrophile to afford a substituted derivative 2. P is typically a lower alkyl group, but can be a protecting group that is removed later in a synthesis. When P is a lower alkyl group it can possess functionality initially, or be derivitized to contain such functionality at various stages of the synthesis. The group, E1, represents either a protecting group, for example benzyl, or a group that either has moieties present in compounds of the invention or possesses functionality that serve as a precursors to such groups. Aromatic ring nitration and reduction of the corresponding nitro group are carried out in a regio- and chemoselective manner by methods well known in the art to give anthranilate derivative 3. Formation of quinazolin-4-one 4 is carried out by methods well known in the art, for example by heating 3 in formamide solution in the presence of ammonium formate, or for another example by heating directly with formamidine hydrochloride. Introduction of 4-position functionality is carried out by methods known in the art. For example, quinazolin-4-one 4 is converted to an intermediate quinazoline 5, where “L” represents a leaving group, for example chlorine. Quinazoline 5 is then converted to 6 by reaction with a range of nucleophiles, for example amines, alcohols, and thiols. After formation of 6, group “Z” is either left “as is” or converted at some subsequent stage to a derivative thereof. For example when Z is —NH—, then the hydrogen on the nitrogen may optionally be replaced with an alkyl group, or when Z is sulfur, then that sulfur atom may be oxidized to, for example, a sulfone. Compound 6 may represent a compound of the invention or, for example when E1 serves as a protecting group, E1 may be removed to provide phenol 7. Introduction of a group E2 is carried out by methods well established in the art, for example alkylation with an appropriately derivatized alkyl halide.

The insoluble support may be made of any composition to which the compositions can be bound, is readily separated from soluble material, and is otherwise compatible with the overall method of screening. The surface of such supports may be solid or porous and of any convenient shape. Examples of suitable insoluble supports include microtiter plates, arrays, membranes and beads. These are typically made of glass, plastic (for example, polystyrene), polysaccharides, nylon or nitrocellulose, Teflon™, etc. Microtiter plates and arrays are especially convenient because a large number of assays can be carried out simultaneously, using small amounts of reagents and samples. The particular manner of binding of the composition is not crucial so long as it is compatible with the reagents and overall methods of the invention, maintains the activity of the composition and is nondiffusable. Exemplary methods of binding include the use of antibodies (which do not sterically block either the ligand binding site or activation sequence when the protein is bound to the support), direct binding to “sticky” or ionic supports, chemical crosslinking, the synthesis of the protein or agent on the surface, etc. Following binding of the protein or agent, excess unbound material is removed by washing. The sample receiving areas may then be blocked through incubation with bovine serum albumin (BSA), casein or other innocuous protein or other moiety.

One measure of inhibition is K. For compounds with IC₅₀'s less than 1 μM, the K_(i) or K_(d) is defined as the dissociation rate constant for the interaction of the agent with ephrin or EGFR. Exemplary compositions have K_(i)'s of, for example, less than about 100 μM, less than about 10 μM, less than about 1 μM, and further for example having K_(i)'s of less than about 100 nM, and still further, for example, less than about 10 nM. The K_(i) for a compound is determined from the IC₅₀ based on three assumptions. First, only one compound molecule binds to the enzyme and there is no cooperativity. Second, the concentrations of active enzyme and the compound tested are known (i.e., there are no significant amounts of impurities or inactive forms in the preparations). Third, the enzymatic rate of the enzyme-inhibitor complex is zero. The rate (i.e., compound concentration) data are fitted to the equation:

$V = {V_{\max}{E_{0}\left\lbrack {I - \frac{\left( {E_{0} + I_{0} + K_{d}} \right) - {\sqrt{\left( {E_{0} + I_{0} + K_{d}} \right)^{2} - {4\; E_{0}}}I_{0}}}{2\; E_{0}}} \right\rbrack}}$ Where V is the observed rate, V_(max), is the rate of the free enzyme, I₀ is the inhibitor concentration, E₀ is the enzyme concentration, and K_(d) is the dissociation constant of the enzyme-inhibitor complex.

Another measure of inhibition is GI₅₀, defined as the concentration of the compound that results in a decrease in the rate of cell growth by fifty percent. Exemplary compounds have GI₅₀'s of, for example, less than about 1 mM, less than about 10 μM, less than about 1 μM, and further, for example, having GI₅₀'s of less than about 100 nM, still further having GI₅₀'s of less than about 10 nM. Measurement of GI₅₀ is done using a cell proliferation assay.

Tyrosine kinase activity is determined by 1) measurement of kinase-dependent ATP consumption by in the presence of a generic substrate such as polyglutamine, tyrosine (pEY), by luciferase/luciferin-mediated chemiluminescence or; 2) incorporation of radioactive phosphate derived from ³³P-ATP into a generic substrate which has been adsorbed onto the well surface of polystyrene microtiter plates. Phosphorylated substrate products are quantified by scintillation spectrometry.

Materials and Methods

Kinase activity and compound inhibition are investigated using one or more of the three assay formats described below. A brief summary of assay conditions is listed in Table 2. The ATP concentrations are selected near its Michaelis-Menten constant (K_(M)) for each individual kinase. Dose-response experiments are performed at ten different inhibitor concentrations in a 384-well plate format. The data are fitted to a standard four-parameter equation listed below: Y=Min+(Max−Min)/(1+(X/IC ₅₀)^H) where Y is the observed signal, X is the inhibitor concentration, Min is the background signal in the absence of enzyme (0% enzyme activity), Max is the signal in the absence of inhibitor (100% enzyme activity), IC₅₀ is the inhibitor concentration at 50% enzyme inhibition and H represents the empirical Hill's slope to measure the cooperativity. Typically H is close to unity. These parameters are obtained by nonlinear regression algorithm built into ActivityBase software (available from ID Business Solutions Ltd., of Guildford, Surrey, UK). ³³P Phosphoryl Transfer Assay (Radiometric)

Greiner 384-well white clear bottom high binding plates (available from Greiner Bio-One, Inc., of Longwood, Fla.) are coated with 2 μg/well of protein or peptide substrate in a 50 μL volume overnight at ambient temperature. The coating buffer contains 40 μg/mL substrate, 22.5 mM Na₂CO₃, 27.5 mM NaHCO₃, 150 mM NaCl and 3 mM NaN₃. The coating solution is aspirated and the plates are washed once with 50 μL of assay buffer and padded dry. Subsequently compounds and enzymes are mixed with γ ³³P-ATP (3.3 μCi/nmol) in a total volume of 20 uL in suitable assay buffers (see Table 2). For example the final EphB4 reaction solution contains 20 mM TrisHCl, pH 7.5, 10 mM MgCl₂, 0.01% Triton X-100, 0.1 mM NaVO₃, 5 nM EphB4 enzyme and 5 μM ATP. The mixture is incubated at ambient temperature for 1.5-2.5 hrs as indicated in Table 2 and stopped by aspirating using an EMBLA 96-head washer. The plates are subsequently washed 6-12 times with PBST or TBS buffer. Scintillation fluid (50 μl/well) is then added, the plates are sealed and activity assessed by liquid scintillation spectrometry on a Perkin Elmer MicroBeta TriLux (available from PerkinElmer Life and Analytical Sciences, Inc., of Boston Mass.).

Luciferase-Coupled Chemiluminescent Assay (LCCA)

In the LCCA assays, kinase activity is measured by the ATP consumption that is accurately measured by luciferase-coupled chemiluminescence. Greiner 384-well white clear bottom medium binding plates are used for LCCA. Briefly the kinase reaction is initiated by mixing compounds, ATP and kinases in a 20 μL volume. The mixture is incubated at ambient temperature for 2-4 hrs as indicated in Table 2. At the end of the kinase reaction, a 20 μL luciferase-luciferin mix is added and the chemiluminescent signal is read on a Wallac Victor² reader. The luciferase-luciferin mix consists of 50 mM HEPES, pH 7.8, 8.5 ug/mL oxalic acid (pH 7.8), 5 (or 50) mM DTT, 0.4% Triton X-100, 0.25 mg mL coenzyme A, 63 μM AMP, 28 ug/mL luciferin and 40,000 units of light/mL luciferase. For the LCCA assays, the ATP consumption has been kept at 25-45%, where the decrease in substrate concentration has less than 35% effect on IC₅₀ values compared to the “theoretical” values with no substrate turnover. The IC₅₀ values correlates well with those of radiometric assays.

AlphaScreen

In AlphaScreen, when the donor and acceptor beads are close in proximity, a series of photochemical events will give rise to a fluorescent signal upon light activation. Here we use biotinylated poly-(Glu, Tyr) 4:1 as the kinase substrate, streptavidin-coated donor beads and anti-phosphortyrosine antibody PY100-coated acceptor beads. Upon phosphorylation, the peptide substrate can bind to both donor and acceptor beads, thus gives rise to fluorescence. Compounds, ATP, biotinylated poly-(Glu, Tyr) and kinases are mixed in a volume of 20 μL for 1 hr at ambient temperature using Greiner 384-well white clear bottom medium binding plates. Then 10 uL solution containing 15-30 mg/mL AlphaScreen beads, 75 mM Hepes, pH 7.4, 300 mM NaCl, 120 mM EDTA, 0.3% BSA and 0.03% Tween-20 is added to each well. After 2-16 hr incubation of the beads, plates are read in a Perkin Elmer AlphaQuest reader (available from PerkinElmer Life and Analytical Sciences, Inc., of Boston Mass.). The IC₅₀ values correlate well with those of radiometric assays.

Enzymes were purchased from Proqinase (of Freiburg, Germany) and Panvera (of Madison, Wis.).
